Gerriet,
Check out the function GetCurrentEventKeyModifiers() in the Carbon
Event Manager reference:

Llistening at NSWindowDidUpdateNotification (or probably better:
NSApplicationWillUpdateNotification) is certainly a good idea.
Whenever the modifier keys change (and on several other occasions as
well) an NSApplicationWillUpdateNotification gets send.
When I get such a notification I could, as you suggested, "make the
appropriate modifications to your button based on the state of the
keyboard."
But: how do I get this aforementioned state? [NSApp currentEvent]
might be the key-event, but I am not sure I can rely on this. Maybe
another event came after this and before the notification gets sent.
I would like to have something like [NSApp currentModifierFlags]
(similar to [NSEvent modifierFlags])
Kind regards,
Gerriet.
